gpu crash dump
hi, dmesg shows me this:
[ 28.353961] [drm] stuck on render ring
[ 28.354632] [drm] GPU HANG: ecode 7:0:0x85dfbff9, in gnome-shell [597],
reason: Engine(s) hung, action: reset
[ 28.354633] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 28.354634] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 28.354635] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 28.354636] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 28.354637] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 28.355972] drm/i915: Resetting chip after gpu hang
It's only appear when i try autologin into gnome-session (or budgie.desktop)
right after boot (DM is started automaticaly by systemd).When i start
gdm.service or sddm.servece manually from tty, autologin works.
When I've tried autologin to another WM like fluxbox or xfce4 it works normally
without hang.
After this hang, gdm (or sddm) starts again and i can login to gnome.session
and everything works fine. I've found no other trigger to make this happens
again.</pre>
